Spring loaded Pneumatic piston

[Peter Matteson]

Traditionally we have not been allowed to use them but I have to say I don't see any rule against it this year.

Normally the GDC's round about way to get prevent use of spring return pistons is that you can only use cylinders equivalent to the free order form parts from Bimba which did not include spring return, bore size and stroke. This year <R73 D> only has a maximum bore and stroke.

I'm actually surprised they opened it up this way finally.

Edit: I guarentee that it is asked at least 6 times in the official Q&A anyway because this question is asked every year.
